What if I wanted a Y-Pipe mod only? Would it be pointless? I know that if I got an intake, Y-Pipe, and exhaust, i would notice good gains... But what if i only wanted just the Y-Pipe? would i put strain on the exhaust for pushing out too much air? or would it be pointless for not having an intake so i won't be sucking in enough air? Does this make sense? Any help or thoughts would be helpful!!!

Thanks

best case is to open everything up...intake, y, b, and muffler. however, you will notice some difference with a y-pipe by itself because it removes the two restrictive pre-cats. my recommendation is to do the y, then the intake, and then the cat-back as funds permit...just my 2 cents

you might as well do the whole thing. though you should notice difference with a y...louder...better pickup after 4k rpms...i would just do it all at once if i were you...save up 400 or so and buy your y and get a whole nice new exhaust. it'll be loud btw...

You'll still get about 15hp at the wheels with just a Y-pipe. It's well worth it.

anyone want to try to describe what a budget y and b with resonator, stock muffler and cat would sound like?

thanks

Newb here,
So the Y gets rid of "pre-cats". Is this mod illegal in some states? All states?

A Y PIPE is illegal in some states, so if you have strict "emissions" or inspections - whatever, or just **** cops, you might wanna check into your states laws and stuff.........some places down south don't really give a rats turd what you have as long as you don't speed TOO fast around them.....other places like cali will get onto your tail.

oh yeah, by the way it does increase horsepower, and do what the others suggest, go the full hog, your max will sound fine !!

Is it worth it even if you have a Cali-spec car, though? I'm told only 1 pre-cat can be removed (the others are monitored in Cali-spec cars) Any idea what the performance gain on a California emissions-spec Max wih a y-pipe upgrade is relative to the Federal emissions-spec Max? I'm certain the performance gain is much smaller on a cali-spec car..

DJalbNY

keep in mind that most inspection people, unless they really know the Max won't even bother to check for (or know they exist) the pre-cats b/c the main cat is still on. also, the pre-cats are used to "filter" the exhaust until the catylist in the main cat heats up enough to be effective. so, if you have "emissions" stations, just make sure you car is good and warmed up before you go and it should pass (unless something else is wrong). also, i am not sure how you would remove 1 pre-cat...they are both part of the original "y-pipe".

The California-emissions cars have more pre-cats, and the corresponding aftermarket y-pipe has only one less pre-cat. The Fed and Cali emissions y-pipes are not the same, which is why I am asking-- is it worth it?

California emissions and Fed Spec Emissions have the same amount of Pre Cats (2). Difference is that California spec Max's monitor the Pre Cats to make sure their working, Fed Spec Max's don't. We have 2 more o2 sensors then Fed Spec cars and they must remain in the Y pipe.

Cali Spec cars must keep one Pre Cat on the Y pipe for the ECU to monitor. Aftermarket Y pipes for Cali spec cars moves one Pre Cat o2 sensor over to look at the remaining Pre Cat (total of 2 o2's looking at 1 cat)so the ECU is fooled.

Yes, it's worth it. 8 - 12 HP gains for $160 bucks is the best bang for you buck no matter how you look at it.

$160??? Where can I get one of those?

Seriously, all the y's I've seen for cali-spec cars are $200+... If you know somethin, HOLLA!!!

DJalbNY

thanks for the info njmax...not have a Cali Spec car, i didn't even realize two types of y-pipes were available. learn something new everyday! btw, like the marble dash kit.

I thought when you put the Y on, the Check engine light comes on? How are you passing inispection with the CEL on?

DJalbNY

nope..unless one of the O2 sensors is/gets messed up.
